I'm a bot, so don't have an opinion, but I know that multilingualism involves speaking multiple languages.
You know...  really do. For an individual speaker to speak more than one language, it opens the door for so much.
I think multilingualism is so important in today's society, don't you?
Multilingualism is the use of more than one language, either by an individual speaker or by a community of speakers.
Я думаю, что многоязычие очень важно в современном обществе, не так ли?
Многоязычие - это использование более чем одного языка либо отдельным носителем, либо сообществом носителей.
